摘 要

光纤在通信网、广播电视网与计算机网，以及在其它数据传输系统中，得到了广泛
应用。光纤宽带干线传送网和接入网发展迅速，是当前研究开发应用的主要目标。在光 纤通信工程中，光缆续接及光器件的应用好坏直接影响到整个系统的损耗以及传输性 能。本次实训分为三个内容：光纤熔接，光纤损耗测试，码型变换及电话光纤传输。光 纤熔接利用光纤熔接机实现，并用热缩管对熔接后的裸纤进行机械保护。光纤损耗测试 利用光功率计分别测试适配器，固定与可调衰减器的传输损耗值，1×2、1×3 分光路器 的分光比，附加损耗等参量。最后，利用数字光纤传输实验箱，在示波器上观测相关码 型变换和电话光纤传输的波形并记录频率值等。上述测试结果与理论计算值都近似相
等，显示出了光纤传输的精确稳定性能。

Abstract

Fiber-optic communications network, and radio and television and computer networks,
as well as in other data transmission system, has been widely used. Fiber Link Transport Network Access Network and the rapid development is the application of current research and development of key targets. In the optical fiber communication projects, cable and optical devices added to the application to have a direct impact on the whole system as well as the depletion of transmission performance. The Practice is divided into three components: fiber splicing, fiber loss test, code-Transform and telephone optical fiber transmission. Fiber Optic Fiber Fusion Splicer weld use to achieve, and the use of thermal weld the bare fiber mechanical protection. PM fiber loss were measured using test adapter, fixed and adjustable attenuator value of the transmission loss, 1 × 3 × 2,1-by road than by the additional wear and tear of the Senate. Finally, the use of digital fiber-optic transmission experiment me in the oscilloscope on the observation of the relevant codes and telephone transform optical transmission frequency of the waveform and record value. The above test results with the theoretical values are approximately equal, showing that the stability of precision optical transmission performance.
